I have to set up security cameras around a construction site, so the first camera I put up is right outside my office. about 50ft. up a light pole. I am running coax for the video and catv for the power, pan, and tilt. The camera is getting power, but my video is extremely foggy and unfocused. I have the catv running to a RS485 adapter to a RS232 in the back of my optiview computer running widows xp. I can't get the camera to zoom or focus, pan or tilt in any way and can't get rid of this foggy picture. So I hooked up another camera in my office, using a short coax and the speed dome's own cables for the RS485 connection and power. I got the same problem, an extremely foggy and distorted picture and no controls at all. any help would be great.

it's an optiview speed dome and is rated for outdoors. the one I have inside is having the same issue. just a really dark, distorted picture. it worked fine (picture wise) for about an hour while I was fiddling with the rs485 cables trying to get control. so, appearantly the auto focus isn't working and I have no control of the cameras. can any one help me fix it?
